An opinion piece by SA Secular Society’s Declan Ahern.
Every September 24th, South Africa has a national tradition. The smell of braai smoke fills the air, people wear bright, traditional clothes, and we celebrate our “heritage.” We get together and tell ourselves this day is about honouring the many different cultures and traditions that make up our country. It’s a beautiful picture of unity. But what if this surface-level celebration is hiding a deeper, more important truth?
The common story of Heritage Day is a simple one. It’s like a museum with separate exhibits for each culture, each with its own history and customs. This simple idea lets us appreciate our differences without ever really looking at what we have in common. But science, like a powerful light, shows us a different story, one not of separation, but of constant connection and shared history.
Birthplace of humanity
Think about the Great Karoo. Don’t just look at cultural displays; look at the fossil beds. Here, the bones of our earliest ancestors tell a different, much older story. Southern Africa is the birthplace of humanity, the place where all people on this planet first came from. The evidence from genetics and archaeology doesn’t show separate, tidy groups; it shows constant movement, mixing, and change. Our DNA is a living mix of this shared, migratory past. The idea that we are a collection of separate tribes is a modern concept. Our truest heritage is the real, unedited story of a single, connected species. The braai is a nice tradition, but our real heritage is the fire itself, the tool that allowed us all to survive and thrive together.
The S A Secular Society in its scientific view of the world doesn’t disrespect our cultural stories; it puts them on solid ground. It frees us from needing supernatural answers and points us toward the actual, amazing story of how we came to be. Is there not more wonder in the complex story of human evolution than in a mythical creation tale? By using a scientific lens, we aren’t getting rid of our ancestors. We are honouring them with the most powerful tool for understanding that we have: reason.


Our modern scientific institutions are a strong example of this ancient quest for knowledge. The Square Kilometre Array (SKA), for example, isn’t a magical observatory; it’s a team effort, based on logic, to understand our place in the universe. It shows what we can achieve when we come together based on evidence and curiosity. The SKA is as much a part of our modern heritage as the ancient rock art of the San people. Both are attempts to make sense of the universe, one with myths and art, the other with math and physics. A truly honest appreciation of our heritage embraces both, showing how far we have come.
Our collective journey
This path requires courage. It means letting go of comfortable myths and facing the complicated, often messy, but much more truthful story of our collective journey. It means seeing that the lines that divide us are often far less real than the biology that connects us. This isn’t about erasing our history; it’s about making it stronger. By understanding our shared origins, we can move from simply tolerating each other’s differences to celebrating our fundamental family ties.

Closing thoughts
So this Heritage Day, let’s do more than just light a fire. The South African Secular society invites you to light a flame of curiosity. Let’s move from simply observing to actively seeking answers. The invitation is to see our heritage not as a museum of the past, but as a living, breathing story that is still being written. The best way to honour our past is to make sure our future is built on the solid, shared ground of evidence and reason, not on the weak foundation of myths and division. We can’t build a strong, unified nation on stories that separate us. We must build it on the reality we all share.
